Two renewables giants with a hefty global reach are facing debilitating financial crises. SunEdison on the Verge of Bankruptcy California-headquartered solar project developer SunEdison, a company that has 1,000 operational sites worldwide and is staffed by 3,000 employees, is facing a liquidity crisis so dire, the company’s yieldco TerraForm Global warned in a March 29 […]

Portland General Electric (PGE) assumed engineering, procurement, and construction (EPC) responsibility for the Carty Generating Station on Dec. 18, following the original EPC contractor’s default on its construction agreement. Construction began on the Carty plant on Jan. 9, 2014. It is being built in Oregon next to PGE’s existing Boardman Plant, which is scheduled for […]

The global concentrating solar power (CSP) sector, criticized by some observers for high costs and uncertain technology, is poised for significant growth and a key role in the power mix—provided markets are structured to properly value their ability to store and dispatch renewable energy, three senior CSP executives said on Sept. 16. Speaking at the […]

Concentrating solar power has found a partner in thermal storage, but costs remain high. Solar photovoltaic generation may have a partner in rapidly expanding battery options, but the economics are uncertain. Is there room for both approaches, or will one be crowded out? Battery storage is officially hip. Once a subject of concern largely only […]

Everyone loves efficiencies. Combining generation technologies can create a plant that’s more than the sum of its parts, but engineering challenges mean these projects are not for the faint of heart. When you think of “hybrids” these days, your first thought is probably of automobiles. But hybrids—hybrid power plants, that is—are starting to emerge in […]

Abengoa’s Solana solar thermal plant, the world’s largest parabolic trough concentrating solar power (CSP) plant and the first in the U.S. with thermal energy storage, began commercial operations on Monday. The 280-MW plant, near Gila Bend in Arizona about 70 miles southwest of Phoenix, employs molten salt to store about six hours of thermal energy […]
